Originally posted by LesDMess It is very convenient to use the Taks on an aperture priority camera. Just focus, stop down and fire. Easily my favorite setup and probably the smallest fisheye setup.
while I would almost universally recommend a proper screwmount body such as a spotmatic (the desire for a light meter kills my recommendation for the greatest pentax ever made) LesDMess, makes a good point here. if you will be using this camera soley with screwmount lenses, you can buy a pentax kmount adapter, lock it into place and forget about it. this gives you the convenience of not only a light meter, but Av style AE, a more compact body, a bigger brighter viewfinder, improved metering and other benefits over an older screwmount body. an MESuper like shown above or maybe a SuperProgram, would make excellent choices for a dedicated screwmount body.
(although he's wrong on the last part as that would be an MX with the even smaller 18mm fish-eye-takumar
)
